In case you’re keeping track — this is the third crib Matt’s tried to unload in the last two months — he listed a condo in the posh Sierra Towers in August, and his Malibu beach pad just a few weeks ago.

The new listing comes in at a spacious 4,100 square feet — and has 3 bedrooms, 4bathrooms, a media room … and walls of windows to show off the smoggy view of downtown L.A.

Perry bought the hilltop home for $4.475 million in 2008 — so he’s hoping to make a pretty penny off the sale.
